I wish I got throughput over the network of 20GB/S. The 20GB/S R/W speed is local, on the flash server itself. That's the performance of 24 drives in a RAID Array, VM created on the array, disk test run within the VM.Well, it seems you have a very good backup strategy already. Because you were able to boot the local Thunderbolt backup and clone it to a spare SSD, you should try to boot from a USB bootloader and select the spare SSD at the Clover Boot Menu. If necessary, you can build a new USB bootloader by following the UniBeast instructions in the first part of the installation guide (post 1 of this thread).
I use the following components:
MacOS will happily boot right from the USB 3 enclosure. I have never encountered any problems with this approach -- no freezing or stuttering.
This is very interesting.
- Is your NVMe block storage a Thunderbolt 3 device connected over one of the two on-board Thunderbolt 3 ports?
- And you're getting 20GB/s read/write speeds (160 Gbits per second)? May I ask you to double-check this with Blackmagic Disk Speed Test and perhaps post a screenshot?
- I'm curious because Thunderbolt 3 operates over four PCIe lanes and has a theoretical maximum of 40 gigabits per second (much lower than 160 gigabitsper second).
Throughput over the network is pathetic. I've been running Dual 40GbE and trying dual 100GbE, amongst other options. I'm six months into testing solutions to achieve superior network performance.
I have a separate quad NvMe array which is thunderbolt, for local DAS. That has a potentially bootable backup but it doesn't show as an available drive to boot to.
I'm about to start troubleshooting now.
